CONCORD, Mass.--(BUSINESS WIRE)--Oct. 10, 2001--
SolidWorks Corporation today announced that Dresser Inc., a global
manufacturer and marketer of highly engineered equipment used
primarily in the energy industry, will extend its use of SolidWorks
three dimensional computer-aided design (3D CAD) software to hundreds
of engineers in its equipment design groups. Dresser currently owns

learn," said Brian White, Dresser's vice president of technology.

design time and minimizes production errors, enabling us to get
products to market faster. We look forward to working with SolidWorks

engineering groups."
